To all whom it may concern:

Be it known that l, CARL Nnusns, a citizen of the United States of America, and a resident of Baker county of Baker, and State of Oregon, have invented certain new and useful Improvements in Acetylene Miners Lamps, 01'' which the following is a full and clear specification.

The object of this invention is to provide a simple practical lamp of this type that will to a high degree fulfill the demands of the practical miner as more fully hereinafter set forth.

In the drawing- Fig. l is a perspective View showing one way of supporting the lamp;

Fig. 2 is a similar view, showing another way of supporting the lamp and also one way of protecting the flame from dropping Water; I

Fig. 8 is a vertical sectional View of the lamp;

Figs. & and 5 are horizontal sectional views taken respectively on the lines 44 and 5-5 of Fig. 3.

This lamp is made in two main cylindrical parts a and b, the part a being the waterchamber and the part I) being the carbidechamber. The carbide-chamber is closed at its bottom, and rising from this bottom wall is a central tube a threaded exteri'orly at its upper end and provided with numerous perforati'ons along its length. Its upper threaded end is adapted to be screwed into a nipple (Z depending from the bottom wall oi the water-chamber, the upper end of the nipple being threaded for detachable connectionto said bottom Wall, this detachability being desirable in order to permit removal of this nipple for the purpose of cleaning and repairing the water-valve 6 carried by this nipple. This water-valve is spring-actuated to its seat in the upper end of the nipple and it is provided with a pin f long enough to depend into the upper end of the tube 0. This feed-valve is adjusted by means of an abutting rod 9 extending up through the tube 0 and threaded at i into the lower extremity of said tube a, the projecting end of the rod 9 being provided with a thumb-piece i for convenience in ad justing the rod, this thumb-piece being convexed upwardly to enable it to lit up into the convexed bottom wall of the carbidechamber, so as to be in a measure housed by said bottom wall in such manner as to be out of the Way.

It will be observed that the bottom wall of the water-chamber forms the top Wall of the carbide-chamber when the carbide-chamher is screweclinto place by means of the tube a, and nipple d, the upper rim of the carbide-chamber entering a packed groove around the outer edge of said bottom wall. From the bott'dm wall of the water chanrber extends a gas-tube y whose upper end extends up through a central. hole in the top-plate is and is flared inte'riorly at its upper end to receive the removable burner-tip Z of the usual construction. Around the upper end of the gas-tube, the top-plate is is provided with a series of small openings m to provide for "an air supply to the flame. 'A sufficient quantity of air is admitted to the water-chamber through the filling-opening a formed in said top-plate is, and the air that passes up through the openings on is confined to the flame by means of a short tube =0 screwed to a central upstanding nipple on the top wall In, this tube 0 being pro- Vic-led with angular sides to permit application thereto or a wrench. The filling-open ing at is closed by a rotary cover p mounted on the top wall is, this cover being loosely confined to the plate by means of the nutl-ike tube 0 through the medium of "a coilspring 9 coiled around said tube 0 and confined between an annular shoulder thereon maths upper face of said cover-plate go, this cover-plate being provided with an open ing 7' which when the cover is turned, is adapted to register with the filling-opening a. It will be understood that while this cover 39 is tight enough to prevent accidental terms-git is not tight enough to prevent the ingress or sufiicient an to supply the openings m with suilicient air to give a white flame; W

Extending through the watenchamber a at a point above the center of gravity of the lamp is a rigid tube 8 open at both ends. Throiigh this tube is passed a skewer 23 which mana er a rod pointed at one end and provided with a fin er-receiving ring-handle t the otherend. it putting up the lamp, a is simply necessary to pass the skewer throughthetub'es and then push or drive the pointed end of the skewer into the mine timber. The skewer passes leos'ely through the tube 5 so that the temp swings on the tube in the manner of a pendant, thus always maintaining an upright position and relieving the miner entirely of the bother ofholding the lamp upright during the driving of the skewer into the timber of the mining chamber.

For use 1n those cases Where it 1s impossible or inconvenient to support the lamp on the skewer, I provide a hook u, as shown in Fig. 2. To connect this hook'to the lamp,

I provide another tube 11 which enters the water-chamber at right angles tothe tube 8 and has its inner end supported on said tube 8 by a T-coupling sr At the inner endof the short-tube o,'i. e., in couplings", I provide a series of internal screw-threads w into which the threaded end of the hook it may be screwed. The end of the hook is screwed loosely intothe threads to so that the lamp rm '1 arran ed between the s rin t and J b b said cover plate. It will be observed that the shape of the hook it enables it to be readilyfscrewed home in, the tube o, the hook part serving as a sort of crank, and it will be observed also that it maylbe screwed far enough to cause pin a formed on its inner end to passv through an opening a formed in the tube a, so that when. desired this hook may be used to lock the lamp from sliding oif the'skewer, said pin a being arranged to enter an annular groove a formed in the skewer. To properly locate this groove at with respect to .pin 14 the skewer is pro-. vided witha shoulder a to limit its, passage through tube 5'. i

It will be observed that a featureof importance is that the lamp will always hang straight on the skewer. or hook, whichever support is in use; and another feature is that when the feed-valve is once adjusted it will automatically shut oif when the carbide-container is removed for refilling; and when the carbide-container is again screwed into place, the feed will be restored without again adjusting .the'feedscrew. Another feature ofimportance is the provision of a rotary closure-cap for the filling tank, this cover being held inplacefrictionally so as not to be accidentally opened. Another feature of importance is the location of the air-holes m at a point close to the burner, so that the lamp may be tilted to a con, siderable angle without spilling the water out through said openings. It will be observed also that an advantageous feature is'that the feed-valve may be readily removed for cleaning and repairing.

It will be observed further that a feature of great importance in my lamp is that there 1,4.2o,1ss

are no obstructions around the flame, thereby permitting the iiame to radiate in all directions without forming shadows, shadows being, of course, frequently very objectionable to the miner. In view of this capacity to radiate the light in all directions, the miner will have a wider choice of positions for locating the lamp than would be the case if the light were permitted to radiate toward one side only. In fact, I have constructed my lamp to be as nearly like a candle as possible, since a candle is an ideal illuminating device for mine use, except that its illuminating power is too limited.

. It will be observed also that my lamp is virtually reversible in that the skewer may be passed through the lamp-body from either side, thereby enabling theminer to locate the hook on either the right or the left-hand side of the lamp. This is a great convenience to the miner.

Acrossthe lowerend of the tube j extends.

a small pin 4), the object of which is to hold in place a filling of fibrous material e such as raw cotton, this packing or shield of cottonserving to prevent the carbide particles from passing up into the tube and being deposited therein or in the passages of the burner-tip. This porous mass also prevents moisture from passing up to the burner-tip.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is: v

1. in an acetylene generator and miners lamp, a carbide-chamber, a water-chamber connected thereto and having a burner-tube in its top extending upwardly from its top, a gas-tube extending from said burner through the water-chamber to the carbidechamber, the top of the water-chamber having a loosely-fitting cover to permit air to enter the water-chamber through the top, said top-wall of the water-chamber being provided with an annular series of openings surrounding the burner-tube, and a tube on the top-wall of the water-chamber surround- .ing said perforations and extending upwardl to near the burner-tip.

2. n an acetylene generator and miners lamp, a carbide-container, a water-chamber, a gas-burner in the top of the water-chamher, a shouldered tube secured to a nipple on the top wall of the water-chamber and arranged to surround the burner, said top wall being provided with air-openings within the tube to supply air to the burner, a rotary cover'for the filling-openingsof the water-chamber, and a spring arranged between saidcover and the shoulder on said tube acting to normally press the cover against the top wall of the water-chamber.

3. An acetylene generator and lamp having a burner at its upper end and a supporting tube extending transversely entirely through the water-chamber of its body at a point above the center of gravity and below its top, and a skewer-like support adapted to extend horizontally and rotatively through said tube so as to thereby ensure a normal upright position of the lamp on said skewer.

4:. An acetylene generator and lamp having a burner at its upper end and a supporting tube extending transversely through it at a point below its top, a skewer passing rotatively through said tube and adapted to support the lamp in a pendent position, and means entering the body of the lamp for loosely and detachably locking said skewer to said lamp.

5. An acetylene generator and lamp having a supporting tube extending transversely through it, a skewer passing loosely through said tube and adapted to support the lamp in a pendent position, and means for loosely locking said skewer to said lamp, said locking means consisting of a hook threaded through a tube mounted in the lamp body, the inner end of said hook being adapted to loosely engage a groove in said skewer.

6. An acetylene generator and lamp having a supporting tube extending horizontally transversely through its body at a point above its center of gravity, and a pointed skewer adapted to extend rotatively through said tube from either side, thereby rendering the lamp reversible, said lamp body being provided with a supporting hook extending substantially at right angles to the skewer and having its inner endin detachable locking engagement with said skewer.

7. An acetylene generator and lamp having a burner at its top and a tube extending through its water-chamber at a point above the center of gravity, a skewer rotatively and reversibly extending through said tube, another tube extending into the water-chamher and rigidly connected to the aforesaid tube midway its length, a hook having its horizontally-bent end extending into the latter tube and rotatively mounted therein, the horizontally-extending end of said hook having interlocking engagement with said skewer to prevent the same being withdrawn but to permit the skewer to relatively rotate with respect to the lamp.

8. An acetylene generator and lamp having a burner at its upper end, and a sup porting member therefor having a hook at its upper end having its lower end entering the lamp horizontally, a tube extending into the lamp body andadapted to rotatively receive said horizontal end, and means within the lamp body for engaging and locking the inner end of said horizontallyextending end portion against withdrawal from the tube but not against rotation.

9. An acetylene generator and lamp having a burner at its upper end, a tube extending into the body of the lamp at a point below its top and above its center of gravity, a threaded member at the inner end of said tube, and a supporting member having a hook at its upper end and a horizontally-extending part at its lower end adapted to enter and fit rotatively within said tube, the inner end of said horizontal part being threaded for engagement with the aforesaid threaded member.

In testimony whereof I hereunto affix my signature.
